Determinants of spreading cyberthreats in financial sector

With the onset of the global pandemic, which has provoked the digital transformation of business, there has been a significant increase in the number of cyberattacks on government agencies, private companies, and individuals. The purpose of the article is to determine the reasons for the rapid spread of cyber fraud in the financial sector of the economy and the peculiarities of their implementation. Systematization of literature sources and approaches to the study of financial cyber fraud has shown that the growing number of cyber attacks in the field of financial services is the result of rapid use of innovative digital technologies in financial institutions, the emergence of fintech companies and increasing demand for digital financial products due to the COVID-19 pandemic. The main initiators of cyberattacks and features of their illegal actions in the financial sector are identified. The study found that the most common forms of cyberattacks in the financial sector are ransomware, supply chain attacks, cryptojacking, and destractive attack. The paper analyzes the world's largest cybercrime groups that carry out attacks on financial institutions. It is substantiated that in order to build an effective system to combat cyber threats and ensure the stability of the financial system, it is advisable to take a set of measures aimed at monitoring the information security of financial institutions, combining efforts of national regulators and heads of financial institutions to inform about real and potential competencies in the field of information security by improving the skills of employees of financial institutions and the national regulator. Prospects for further research in this area are to build an economic and mathematical model to determine the determinants of spreading the cyberattacks using data of the European Union countries
